Test Overview. An ammonia test measures the amount of ammonia in the blood. Most ammonia in the body forms when protein is broken down by bacteria in the intestines . The liver normally converts ammonia into urea, which is then eliminated in urine. Ammonia levels in the blood rise when the liver is not able to convert ammonia to urea.
The assay can be used to measure ammonia levels over a broad range, from as low as 12 Î¼mol/L to as high as 1 mmol/L. The disadvantage of this approach is the length and complexity of the procedure, thereby enhancing the potential for variation in reported blood ammonia levels.
